[TEST] touch screen/calibration issues... may have figured some things out? - Nexus One General

Ok, so over the course of time I have owned my phone I think I may have found one of the reasons for the phone to go out of calibration in terms of touch accuracy but I just want to make sure its not just my phone doing it.
What I have noticed is that if I hold my phone at an awkward angle for a few minutes (typically 5ish minutes) the calibration will go out of whack. This notoriously happens when I have my phone in navigation mode and just laying on my lap (landscape mode). Today I was driving and I got a text mid way to where I was going so I picked the phone up to hit the talk-to-text button (which is really nice for texting while driving by the way) and it was out of calibration, could not hit the button to save my life. Similar has happened when I held the phone at an awkward angle while watching a movie laying in bed. So I would like to see if anyone gets similar results holding the phone at an awkward angle for a few minutes, I would say give it 5-10 minutes for an accurate result. Try doing things like holding it literally upside down while its in landscape mode and then switching it back to portrait and type on the small keyboard again. I would go into a program of some sort that you can test touching all areas of the screen with.
Now, it seems like before the OTA update, I would have to reset the phone and sometimes that wouldnt work still. However now (and I have tested multiple times with consistent results) that if you lock the phone and then unlock it, the calibration seems to be adjusted again.
Let me know your results.
**For the record, I have had a very positive experience with this phone since I purchased it but I have been able to replicate the "touch screen issue" many a times and would just like to get to the bottom of the issue if all else to just avoid it or tell others how to avoid it happening to them because it is quite annoying.

it sounds like a software hiccup i would hope it would be getting patched sometime..... but as of now i dont know of anyone that's got a fix for it. i have the problem from time to time but i just lock and unlock and its fine, kind of annoying but not something that makes me want to throw it out the window or anything.

Judging from the behavior, I'll place my bets on it being a software issue rather than hardware. There seems to be some hiccups between the accelerometer and the screen getting confused about angles/tilting.

didnt happen to me before upgrade. Its happened a couple of times since.
My phone had been on charge and I had changed to setting to disable it from sleeping while on charge. I had turned the screen off but it must have woke up I went to use it and couldnt hit any keys.
I thought it may be something to do with it being awake for a long time - but it could be coincidence.
I can confirm that putting the phone to sleep and waking it fixes the problem

I have the same issue. No problem before OTA and described problem after that. Grrr.

Mmm, I experienced the problem both before and after the OTA, so I dunno.

Good to know that you can just sleep the phone and then wake it back up to fix the issue now. You used to have to reboot.
I have not had the issue at all since removing live wallpapers. Maybe just a coincidence.
Do people using custom ROMS have these issues?

Ok, so there are similar results out there then and sounds like 100% confirmed just locking and relocking recalibrates the phone back into proper order, no more full reboot is needed.
For the record, I am not using a live wall paper, I have not rooted or installed any themes or anything so my phone is all stock besides the OTA update. Also, as someone else stated that you used to have to restart your phone before the update and I experienced the same thing but again now I only have to lock and unlock the phone for it to recalibrate.
Grainysand you and I seem to have had similar "issues" if you even want to call them that with before and after the OTA and I share your view that there is an issue between the accelerometer and the software recognition.

It's definitely the accelerometer. For the record, I've never had to either reboot or relock/unlock the screen to fix this. I hold the phone upright and it corrects itself, though sometimes it recurs.

I've noticed this a few times after the ota, but just turned it off/on to fix.

Same here. Usually when in landscape mode and the device is tipped at a 45 degree angle. I've also seen the N1 (when using the browser in landscape) scroll the page back and forth very quickly (about 1/4"). When this happen the device seems to get 'stuck' in landscape mode even when I flip it back to portrait.

After the ERE27 update, I've only really noticed the issue when I've plugged in the charger.

now that I think about it, I must say that most of the time I see this happening it has been on the charger... will test later though, i doubt this would effect the issue

I think it has something to do with live wallpapers, the ones that receive input touch to react in some way or another. Its a software issue.
You could put it to sleep and on wake up its ok.
Or you could touch the buttons slightly to the right.

no its not the live wall papers... I have tested both with and without live wall papers and I can produce identical results as far as loss of calibration

Not sure if its the same problem but when playing games sometimes, the isnput locks up sometimes when in landscape mode. However rotating the phone between landscape & portrait mode seems to fix the problem, might help for this too.

Unlock screen issues

Anyone else having this problem,
Sometimes when I get to unlock screen and swipe across it doesnt react to it the first time and I have to do it again.
Yes. Many, many times. I resolved this by downloading an app that gets rid of the bar from me, so now I press home. Unfortunately this means I have no security on my phone. Yay!
Yea; I mean how much of a problem is it though? I guess it takes a second sometomes to initialize the scanner.
Rooted/ROM Captivate (For Sale)
Rooted Atrix
I am not talking about the finger printer reader, also at work I have about 1 second to check phone, so it just gets annoying when I spend that one second trying to get passed the lock screen
Oh! Yea that happens to me sometimes as well; I hate it.
It also "confuses" me when I slide it but there's nothing really being slid you know? Just the color.
Rooted/ROM Captivate (For Sale)
Rooted Atrix
Never had a problem with slide to unlock.
The finger scanner though, you have to remember at what angle and what direction you scanned in. Finding a comfortable swipe is better than trying to get a correct register. It's kind of like practicing golf swings.
I didn't have this issue till I did a factory reset, now the lock screen is soo slow.

Was going to say same thing. I did my 1.5.7 update a little bit ago and really having seconds from when I hit the power button until my screen wakes up. I can actually hit the button and scan my finger before it comes on. Anyone else having this type of slowdown?
Sorry for bringing up a old thread but kinda based on what I am dealing with.
My Atrix keeps waking itself up after putting it to sleep and STAYING on...
It is killing the battery life. This has only happened since the update...
Solutions?
I had that once before on my old build. Not sure what did it but it did end up stopping after a little bit myself. I think it was an app that was doing it

I would check to see if any apps are causing your phone to wake up; I remember this happening on my Captivate last year. I don't remember what the problem was but I knew it stopped after a week or so.
Something I have noticed with 1.5.7 the supposed fix to allow the phone to sleep while charging was a sinple change in the setting under development. I also have noticed when you place the phone on the charger if the lock screen is up and you are using the fingerprint scanner. you can never ( or should I say rarely) get it to stay asleep as it keeps reading the button press as a finger swipe. The only solution I have found is to make the the phone is on the home screen and press the button to make it sleep. then it stays asleep
I have had things like this happen to me, for a while I was using GingerBlur and I thought thats why the phone was glitching but when I went back to stock I had it glitch like this a few times on me also... I almost feel like my Atrix is running a beta...
I have not had any issues with the slider itself but i have observed this for a few days now. When i slide to unlock the screen, it goes directly to the contacts page and just freezes for a while. no other buttons work except hitting the home button and then ot works as usual. Any pointers? i recently rooted my phone and flashed it with the Alien rom [build #4 - 2.6.32.9]

Issues since updating my Bravo

I would like to start this out by saying that I have had my Bravo since January 16, and have loved every minute of it. This has been my first Android (Came over from my iPhone 3G). I was extremely excited to finally get the upgrade to 2.2, even though I decided to wait to officially download it OTA.
Since I got my phone, I had no more than three to five apps force close on my using the stock launcher. I rarely noticed much of any lag while working with my phone, and I never once had any issues with the phone rebooting itself on me.
Since I updated my phone on Saturday I've been plagued with all of these issues. Immediately after updating, I noticed my phone was running very hot, and my battery drained to 50% within an hour or two without me even running anything stressful on it. I restarted it twice and since then I haven't noticed any significant issues with my battery, or the phone seeming to run it's processor excessively.
But, I have constant lag, making tasks that were extremely quick and easy before the weekend be significantly more difficult and frustrating. Today I've even noticed that the lag is so bad that I am not even able to use Swype because the phone takes so long to register any touch's it doesn't register anything other than the first and last letter I swyped across. In addition, my phone has rebooted itself 3 times within the last three days I've been using it, an issue that has not happened once in the three months before this weekend.
I will regularly be trying to do things on my phone and it will lag, causing the phone to freeze for 20-30 seconds at a time, and then trying to perform every touch it received in those 20-30 seconds in a scant second after it recovers.
I have noticed some issues not regarding lag, but sometimes it has been difficult for my phone to initiate calls. I have tried to call my wife, and it took 5 times before the call would finally go through, it was immediately ending the call right after I pressed the call button.
I love my phone and the capabilities of the Android system. Until now I haven't had any problems at all with it. Can you help me try to figure out what's happening, and if there are any ways to fix my phone? I haven't gotten around to rooting my phone since I've gotten it, but have been planning on it.

Something probably is messed up in the upgrade process.
Simple solution, flash the 2.2 sbf and you should be good.
roadkizzle, Something doesn't sound right at all with your update. I would try to remove the battery for a minute and reboot. If you still have issues I would try a factory data reset. If that doesn't cure your ills then flashing the 2.2sbf as bandroidx suggested may be in order.
Alright, I flashed the SBF file to the phone through RSDLite, and from what I can see it went through correctly. My only question now is do you think I'll need to try to re-install the full update? Or is that similar to what I did?

flashing the sbf already updated your phone to 2.2. You don't need to do anything else
I hope reflashing did the trick for you. That experience sounds nasty...

Well, after a couple of hours of playing with my phone it's seeming better. I have been playing a few games of Worms, and my normal surfing the internet and so far I haven't noticed any real lag. The test will be my day through tomorrow.
I was just really confused because I was following the instructions from the Flashing SPRecovery SBF to a Motorola Droid youtube video, and his SBF file really seemed to only change the recovery screen. It looked like he still had to go through the actual update.zip process to make the actual updates to his phone.
Alright it's official, flashing the sbf did not fix the lag issues. My phone hasn't had a critical malfunction and reboot itself yet today, but the lag is unbearable.
roadkizzle, It sounds like you are still having issues. If you look at the system version in "about phone" in settings menu does it say version 37.4.0.MB520??
Yes, it says Version.37.4.0.MB520.ATT.en.US

what apps do you have installed?
look in task master and get rid of any auto-ends and reboot and see if that makes a difference
Well, immediately after removing the AT&T apps from the auto-end list and rebooting, I thought I noticed some lag initially, but I've let it run for a few days now doing everything I was before and I've not been having any of those issues recently.
I'm not sure what it was. I wasn't very aggressive adding apps to my auto-end list, really just Maps and the AT&T apps. I added maps after a while because when I would use it once it would stay open and I'd notice later on that it would have been a major consumer of my battery, and I couldn't figure out how to close it fully.
Glad to hear things are going better. I had some issues totally unrelated to the apps I had in auto-end but pulling all of them off of auto-end got rid of the issues. Froyo is supposed to minimise the need for having to add apps to auto-end in task manager. Regards
(SIA for the long post)
roadkizzle - my situation sounds very similar to yours and I wanted see if you are also seeing a couple of other symptoms I've seen beyond what you have indicated. This has been an issue from early on for me. At first it seemed to be associated to when the battery was low, but it is now ever increasingly interrupting my use of the phone. I was hoping 2.2 might resolve some of this, but it hasn't.
Background: Purchased/activated phone early Jan 2011; recently upgraded to the 2.2 sys and used the official channels; all apps I've added are lightweight stuff (ex: notepad-type stuff, weather widget) and I have pushed most unused stuff to the auto-end list.
Similar symptoms: I see the same power drain and high CPU usage when using maps/navigator (really evident on a recent trip). Still monitoring if some of that can be attributed to use of the GPS.
I'm getting a similar lag though I wish it was only for the short period you are seeing. I've only rarely been able to just put the phone down and have it responsive when I get back to it. Maps/Navigator were especially susceptible to this problem, and it seemed consistent with the 90%+ CPU usage often seen when they are running.
I don't use swipe, but the keypad is most often what is being used when the lag kicks in... the entire phone just goes completely unresponsive, including any and all other input such as the hardware home/back keys, etc.
In addition: Better than half the time that the qwerty touchpad becomes unresponsive, I see sporadically entered random keystrokes to my messages... everything from initiating the voice input to entering several dozen spaces or just simple random characters. This happens at a random, often changing rate and I see the keys lighting up and the haptic responses happen as if I were touching the keys, but they are not from any delay in the input. Once ruling out an exorcism, this has started me thinking I might have a hardware issue with the touchpad. The phone has not been dropped or roughed up in any way, so if it is HDWR, it's a manuf issue.
Luckily.... in 99% of the cases where this happens, using the HDWR power button to cycle the screen through a sleep and back resolves the issue. Not a big deal unless you have to do it 3 times to send one text/mail. This has me constantly thinking about items on the auto-end list but I have not unearthed anything to support that.
The other 1% of the time I have had to reboot the phone, but in those cases I can't rule out 'user issues' due to just pure frustration. Task Manager has become my most freq used app, but often I see everything at 0% CPU and/or not running.
I'm wondering if any of these additional symptoms sound familiar...
thx.

Try taking things off of the auto-end list. You shouldn't need the task killer because android manages apps on its own (it's supposed to manage apps better in froyo than in 2.1)
I've also had lag, especially when opening maps (the first time I open maps it often force closes).
Can anyone get the "lock pattern" screen without the slide to unlock? It seems like a common "Motorola 2.2" issue, but I can't figure out if it gets resolved through an update or not

[Q] Verizon G2 buggy touch screen?

Is anyone else having issues with the touch screen triggering at different places when touched, or randomly knocking off the phone when you're not even touching the phone? I turned off my knockon feature, but I would see my notification bar be highlighted without me touching it. Just wondering if i'm the only one with this problem.
No issues at all.

this glitch is kinda what happened with mine, and i confirmed what it was doing
in swiftkey, you know how tehre's the option to change the long press delay? well i was holding down that little bar to drag it down, and i noticed while holding it inplace, the numbers were going crazy..it was going up/donw/up/down incredibly fast, instead of just staying stationary..i was like, wtf? so i went to dev options, turned on show touch points and the trace so i could see the axis, and i noticed it was freaking out. holding my finger in place, it was as if it was moving around like crazy.
so i did a factory reset and flashed the clean verizon rom scott posted, and it hasn't done it since. no idea wtf was going on. i realized it was messing up bc my typing became really bad, and it would enter things i didn't type.
Touch Screen has a mind of its own - bad digitizer??
I woke up today to find my screen on, showing the lock screen which I found odd. Now most of the time the screen has a mind of its own where basically its like an invisible finger is randomly touching the screen at a frantic place. This opens up apps, moves icons around, calls people if the phone app manages to get opened, etc. After struggling to override the "invisible finger" I've done a reboot from the power menu, powered off from the power menu and left it off for 10 minutes before turning off and held down the power and volume down button to reboot. None of these methods fixed the problem0
Please note I did accept the Verizon update but was good on it for a day prior to this issue. I have installed minimal 3rd party apps and can't attribute the problem to starting right after installing something. I do use the Ghost 100 wireless charger but have been using this from day 1 without issues so I don't think that'a problem either. The Verizon store sold me this charger and although its not listed as being compatible on Verizon's website I have a feeling that's cause the phone is so new. The charger is WPC certified. Being that this problem is intermittent (happens way more often than not) I think it may be a software issue and I'm about to do a hard factory reset. If that doesn't work then I'm convinced its a hardware issue and probably a bad digitizer. I've been very gentle with the phone - haven't dropped it, no moisture or water exposure, not rooted, etc. I'll report back if the factory reset works. Anyone else having the same or a similar issue?

You're not alone! My G2 has been driving me crazy the last couple of days when trying to use the lockscreen. It'll spaz out and either skip a connection of display a whole different pattern than I drew. It will also shut off the screen and reset the "wrong password" counter. I love this phone but this is super aggravating!
Hard reset didn't help at all. I went to a Verizon store and they exchanged for a new one and determined I had a hardware failure.

Weird screen jitter/touch ..phone going crazy

Occasionally my phone will just go crazy, screen will get all jittery,touching on a menu doesn't work ,it mainly happens on noughat stock and custom ROMs.,random apps popping up.any experience anything like that?a simple reboot fixes the problem.

It's an inherent issue with some displays present on the Moto G4. It most often happens when you charge your phone. Too much current builds into the frame of the display and you get weird ghost and jitter touches.
No way around it unless you send it in, and even then it may be only a temporary fix.
I also face this issue. Unable to find solid solution for this. Finally i decied to go for custom rom like RR and Invicta. This still comes occasionally(when Heats too much during phone charging)

On my phone this happens while not charging. Seems to happen about one out of every 3 times the phone is unlocked using the fingerprint sensor. Locking the screen and unlocking via a pin seems to be a reliable way of getting past the issue. Though occasionally it happens on the pin entry screen before it the pin has been entered. Needless to say, it IS annoying.
Same problem which is fixed.
I had this problem with the factory firmware too, intermittent bouts of the phone going crazy with phantom touches on my Moto G4. I sent it to Motorola/Lenovo after the supplier gave me their phone number and they did find the problem and fix it. Now I can play graphic intensive games even during fast charge and the phone is awesome for once. : )
Please note they will fix it for free if in warranty and bootloader not yet modified.
Pressing power button to turn off the display and then pressing power button again to turn the display back on will provide temporary relief from jittery screen. I noticed that the jittery screen has twice subsided over time but came back twice immediately after OS upgrade so blaming the problem on charging, or hardware doesn't seem accurate.
Updated 5/20/2018
As a last ditch effort prior to buying a replacement phone I deleted all apps I installed, reset phone and reinstalled fresh copies of most if the apps I needed.
I don't recall every thing I did but my focus was to delete everything I could and then reset phone back to factory state. After reinstalling, my jittery problem went away and has not returned. Your millage may very, so no promises. Phil

phone going crazy
Hi,
I am having the same exact problem. I have observed that Google Assistant is intruding because each time this happens, Google Assistant is trying to run. Reboot is a temporary fix but the problem persists. I have removed most of the third party apps just to see if anything changes but it did not work.
This is not something that was happening from the start. I have the phone for about 2 months put the problem only started a couple weeks ago. I would love to hear if there is a solution and what. Thanks
Sadly, but compared to the issues visible indoors, in outdoors this Lenovo gift turns complete crap:
youtu.be/dTcHclVEfCg
"Lenovo Moto Z2 Force touchscreen gets completely unusable when getting outdoors! The video is made at about 0 degrees Celsius. So it takes about 30 sec from getting MotoZ2 Frc to sleep with pwr btn (and wakeing up back) to see the touchscreen goes crazy. At -10C, it takes ~5 sec. At +15-20C, after several min it becomes unresponsive and have to use pwr button to recover.
Lenovo, what you have done to Motorola ?!!"
Can it be fixed somehow with changing the upper protective part? I have seen comments that the touchscreen can stop working completely, if peel off the cover part..

Ghost touch issue

It seems my phone has a problem of ghost touch. The status bar slides down automatically and randomly. I turned on developer mode to see what happened, it seems, some coordinates near (320, 0) are clicked very often with no reason at all. It annoys me a lot since it interrupts my normal operation. Did someone has the same problem? And how do you solve it? Thanks
I had the same issue. top right of my screen would think it was being touch when it wasnt.
Yes, my wife's ph-1 has this issue. the ghost touches liked a bunch of Instagram posts, it was hilarious seeing my wife's reaction to this, and then she had to go back and unlike a bunch of crap posts.
But this is an issue and very serious one. I believe this could be also causing battery drain if it interacts with OS and causes deep sleep not to kick in when it should. If the issue happens again I will be contacting support to get this BS sorted out.
I have this issue on the oreo beta although it will keep touching the same spot continuously for about a minute or so and if it happens while the phones locked i cant do anything till it stops luckily its been happening less and less often
I had this happen on one phone but not the others, worse when the phone got hot
i think it's the screen, if you look closely, its not flat. Mine is kinda wavey at the edges, like there's a little too much adhesive, and i think that waviness gets worse when the phone gets hot, and causes the phantom touch

It was gone for 3 days and now the problem is back today. I tried to restart in safe mode and problem is still there so it is a system issue, not caused by third party app.
Same issue here. No rhyme or reason I can see as to why
Mine was happening on my old PH-1 without the earpiece screen, but i got the new version i got has no issue.
This issue is very annoying I'm thinking of returning the device to Sprint and getting another but since it happens so random I wouldn't even be able to show them the issue. Thought it was an issue with the oreo beta but after going back to stock I still have the issue starting to regret buying this phone
I've never experienced this issue on mine
Bump. Been happening to me on Oreo beta. About once or twice a day it happens. I just lock and unlock the phone and it stops. It's weird. I think it has something to do with the screen sensitivity. It's more prone to happening when the device screen is all smudgy or if I just washed my hands.
I have the same issue too.

Me too
Same issue here as well. I did the touch sensitivity trick as well and still getting it. Hope its a software issue and not a hardware one.
I haven't encountered ghost touch but encountered slow responding touch issue. Sometimes the touchscreen will respond to my command slower like 3-4 secs after i touch the screen. Every time this issue appears, a restart of my phone will clear it. Very likely software issue. I'm still on nougat, hopefully they fix it on Oreo before it goes out of beta.
My first PH-1 would become touch unresponsive for 30+ seconds all the time (it was fully updated at the time). It seemed to happen more frequently when I was typing on the stock keyboard. I eventually returned it and bought another several weeks later. I've had no issues with the new one-quite happy with it. I'm running the Beta2 update and enjoying it.

That's good to know. Mine also happened when using the keyboard occasionally as well. I have a replacement set coming as my original set's packaging did not come with the pull tab on the box and there was a fingerprint smudge at the back of the phone when i took the phone out of the box the first time. I presumed mine was a used/returned set, not new as what i had ordered. Hope the new set fixes the issue.
My phone has the same issue whenever I'm charging it and using it at the same time it's registering multiple touches when I'm using just one finger on the screen, it mostly happen when I'm doing a long press action. In developers option I have show taps enable so I'm able to see all ghost touches.
I fixed my ghost touch issue with a simple hard reset.
It will come back sadly
